Terminology

All of the following terms are valid in the context of a specific Wordle.

  • A set of known letters is a set of letters which are known to be present in the Wordle’s word based on clues obtained from the previous attempts.

  • A set of valid words at any given point refers to a set of words from vocabulary that are possible solutions to the Wordle at that point based on the clues obtained till then.

  • A letter is said to cover a word if the letter belongs to that word.

  • Coverage (absolute) of a word refers to the percentage of valid words (at that point) covered by the letters in that word.

  • Coverage (relative) of a word refers to the percentage of valid words (at that point) covered by the set of

Solver

Solver roughly uses the following strategy,

  • Guess a word with highest (relative) coverage.

  • After each guess, eliminate words based on the clues, e.g.,

    • Remove all words that contain an incorrect-letter

    • Remove all words that do not contain the identified (correct-letter, correct-position) combinations

    • Remove all words that contain the identified (correct-letter, incorrect-position) combinations

    • Remove all words that do not contain a correct-letter

    • Re-calculate (relative) coverage and guess again

  • If at any point, number of valid words drops below number of attempts left, guess the valid words one-by-one.

  • Additionally, there are heuristics to choose a word if multiple words with best coverage-score exist.

Helper

Helper mode can be used to get assistance while solving Wordle from another provider.

  • Suggestions for words will be provided at each step.

  • You may choose a word and obtain result.

  • Enter the obtained result as a ternary string, i.e., a string made of 0, 1, and 2.

    • 0 : (grey) : an incorrect letter.

    • 1 : (yellow) : a correct letter in wrong position.

    • 2 : (green) : a correct letter in correct position.

  • e.g., if the third letter turned green and fifth letter turned yellow in the third party Wordle, then you should input 00201 as the result obtained.
